Should be common sense, but I forgot to mention it anyway:  It'd be
a good idea to have it automagically run every one to five minutes
using 'cron', depending on how often you want the thing to check.
The script should abort execution upon the successful ping of any of
the hosts.

If a ping isn't good enough (or, for some freakish reason, ping
works on the gw, but not anything else) then maybe ping the gateway
first, and still go on to ping 3 more hosts, and if all is well with
the first one outside of the gateway, abort.

If you want to test other things, perhaps pipe something into Telnet
on a random server on port 80 and check if it got a result.  Doesn't
really make a difference if the result is valid... but I assume you
should be able to pipe into/out of Telnet in traditional Unix method...
